Neutropenia: Neutropenic deaths have been reported. Monitor for neutropenia with frequent blood cell counts. Jevtana is contraindicated in patients with neutrophil counts of ≤1,500 cells/mm3. Primary prophylaxis with G-CSF is recommended in patients with high-risk clinical features [see Contraindications (4) and Warnings and Precautions (5.1, 5.2)].

Severe hypersensitivity: Severe hypersensitivity reactions can occur and may include generalized rash/erythema, hypotension and bronchospasm. Severe hypersensitivity reactions require immediate discontinuation of the Jevtana infusion and administration of appropriate therapy. Patients should receive premedication. Jevtana is contraindicated in patients who have a history of severe hypersensitivity reactions to cabazitaxel or to other drugs formulated with polysorbate 80 [see Dosage and Administration (2.1), Contraindications (4), and Warnings and Precautions (5.3)].

Indications and Usage for Jevtana

Jevtana® is indicated in combination with prednisone for the treatment of patients with metastatic castration-resistant prostate cancer previously treated with a docetaxel-containing treatment regimen.

Jevtana Dosage and Administration

Dosing Information

​The recommended dose of Jevtana is based on calculation of the Body Surface Area (BSA), and is 20 mg/m2 administered as a one-hour intravenous infusion every three weeks in combination with oral prednisone 10 mg administered daily throughout Jevtana treatment.

Dose Modifications for Hepatic Impairment

Moderate hepatic impairment (total bilirubin >1.5 to ≤3 × ULN and AST = any): Administer Jevtana at a dose of 15 mg/m2 based on tolerability data in these patients; however, the efficacy of this dose is unknown.

Preparation and Administration

Jevtana is a cytotoxic anticancer drug. Follow applicable special handling and disposal procedures [see References (15)]. If Jevtana first diluted solution, or second (final) dilution for intravenous infusion should come into contact with the skin or mucous, immediately and thoroughly wash with soap and water.

Do not use PVC infusion containers or polyurethane infusions sets for preparation and administration of Jevtana infusion solution.

Jevtana should not be mixed with any other drugs.

Preparation

Read this entire section carefully before mixing and diluting. Jevtana requires two dilutions prior to administration. Follow the preparation instructions provided below, as improper preparation may lead to overdose [see Overdosage (10)].

Note: Both the Jevtana injection and the diluent vials contain an overfill to compensate for liquid loss during preparation. This overfill ensures that after dilution with the entire contents of the accompanying diluent, there is an initial diluted solution containing 10 mg/mL Jevtana.

Inspect the Jevtana injection and supplied diluent vials. The Jevtana injection is a clear yellow to brownish-yellow viscous solution.

Step 1 – first dilution

Each vial of Jevtana (cabazitaxel) 60 mg/1.5 mL must first be mixed with the entire contents of supplied diluent. Once reconstituted, the resultant solution contains 10 mg/mL of Jevtana.

When transferring the diluent, direct the needle onto the inside wall of Jevtana vial and inject slowly to limit foaming. Remove the syringe and needle and gently mix the initial diluted solution by repeated inversions for at least 45 seconds to assure full mixing of the drug and diluent. Do not shake.

Let the solution stand for a few minutes to allow any foam to dissipate, and check that the solution is homogeneous and contains no visible particulate matter. It is not required that all foam dissipate prior to continuing the preparation process.

The resulting initial diluted Jevtana solution (cabazitaxel 10 mg/mL) requires further dilution before administration. The second dilution should be done immediately (within 30 minutes) to obtain the final infusion as detailed in Step 2.

Step 2 – second (final) dilution

Withdraw the recommended dose from the Jevtana solution containing 10 mg/mL as prepared in Step 1 using a calibrated syringe and further dilute into a sterile 250 mL PVC-free container of either 0.9% sodium chloride solution or 5% dextrose solution for infusion. If a dose greater than 65 mg of Jevtana is required, use a larger volume of the infusion vehicle so that a concentration of 0.26 mg/mL Jevtana is not exceeded. The concentration of the Jevtana final infusion solution should be between 0.10 mg/mL and 0.26 mg/mL.

Remove the syringe and thoroughly mix the final infusion solution by gently inverting the bag or bottle.

As the final infusion solution is supersaturated, it may crystallize over time. Do not use if this occurs and discard.

Fully prepared Jevtana infusion solution (in either 0.9% sodium chloride solution or 5% dextrose solution) should be used within 8 hours at ambient temperature (including the one-hour infusion), or for a total of 24 hours (including the one-hour infusion) under the refrigerated conditions.

Discard any unused portion.

Administration

Inspect visually for particulate matter, any crystals and discoloration prior to administration. If the Jevtana first diluted solution or second (final) infusion solution is not clear or appears to have precipitation, it should be discarded.

Use an in-line filter of 0.22 micrometer nominal pore size (also referred to as 0.2 micrometer) during administration.

The final Jevtana infusion solution should be administered intravenously as a one-hour infusion at room temperature.

Dosage Forms and Strengths

Jevtana (cabazitaxel) injection is supplied as a kit consisting of the following:

​In a randomized trial (TROPIC) in previously treated patients with metastatic castration-resistant prostate cancer, five patients (1.3%) died from infection (sepsis or septic shock). All had grade 4 neutropenia and one had febrile neutropenia. One additional patient's death was attributed to neutropenia without a documented infection. Twenty-two (6%) patients discontinued Jevtana treatment due to neutropenia, febrile neutropenia, infection, or sepsis. The most common adverse reaction leading to treatment discontinuation in the Jevtana group was neutropenia (2%). Grade 3–4 neutropenia has been observed in 82% of patients treated with Jevtana in the randomized trial.

​In a randomized trial (PROSELICA) comparing two doses of Jevtana in previously treated metastatic castration-resistant prostate cancer, 8 patients (1%) on the 20 mg/m2 arm and 15 patients (3%) on the 25 mg/m2 arm died from infection; of these, 4 deaths on the 20 mg/m2 arm and 8 deaths on the 25 mg/m2 arm occurred within the first 30 days of treatment.

​Fewer patients receiving Jevtana 20 mg/m2 were reported to have infectious adverse reactions. Grade 1–4 infections were experienced by 160 patients (28%) on the 20 mg/m2 arm and 227 patients (38%) on the 25 mg/m2 arm. Grade 3–4 infections were experienced by 57 patients (10%) on the 20 mg/m2 arm and 120 patients (20%) on the 25 mg/m2 arm. Noninferiority for overall survival was demonstrated between these two arms [see Clinical Studies (14)].

​Based on guidelines for the use of G-CSF and the adverse reactions profile of Jevtana, primary prophylaxis with G-CSF is recommended in patients with high-risk clinical features (older patients, poor performance status, previous episodes of febrile neutropenia, extensive prior radiation ports, poor nutritional status, or other serious comorbidities) that predispose them to increased complications from prolonged neutropenia. The effectiveness of primary prophylaxis with G-CSF in patients receiving Jevtana has not been studied. Therapeutic use of G-CSF and secondary prophylaxis should be considered in all patients at increased risk for neutropenia complications.

Monitoring of complete blood counts is essential on a weekly basis during cycle 1 and before each treatment cycle thereafter so that the dose can be adjusted, if needed [see Dosage and Administration (2.2)].

Increased Toxicities in Elderly Patients

​In a randomized trial (TROPIC), 2% of patients (3/131) <65 years of age and 6% (15/240) ≥65 years of age died of causes other than disease progression within 30 days of the last Jevtana dose. Patients ≥65 years of age are more likely to experience certain adverse reactions, including neutropenia and febrile neutropenia. The incidence of the following grade 3–4 adverse reactions were higher in patients ≥65 years of age compared to younger patients; neutropenia (87% vs 74%), and febrile neutropenia (8% vs 6%).

​In a randomized clinical trial (PROSELICA) comparing two doses of Jevtana, deaths due to infection within 30 days of starting Jevtana occurred in 0.7% (4/580) patients on the 20 mg/m2 arm and 1.3% (8/595) patients on the 25 mg/m2 arm; all of these patients were >60 years of age.

​In PROSELICA, on the 20 mg/m2 arm, 3% (5/178) of patients <65 years of age and 2% (9/402) ≥65 years of age died of causes other than disease progression within 30 days of the last Jevtana dose. On the 25 mg/m2 arm, 2% (3/175) patients <65 years of age and 5% (20/420) ≥65 years of age died of causes other than disease progression within 30 days of the last Jevtana dose [see Adverse Reactions (6) and Use in Specific Populations (8.5)].

Hypersensitivity Reactions

Hypersensitivity reactions may occur within a few minutes following the initiation of the infusion of Jevtana, thus facilities and equipment for the treatment of hypotension and bronchospasm should be available. Severe hypersensitivity reactions can occur and may include generalized rash/erythema, hypotension and bronchospasm.

Premedicate all patients prior to the initiation of the infusion of Jevtana [see Dosage and Administration (2.1)]. Observe patients closely for hypersensitivity reactions, especially during the first and second infusions. Severe hypersensitivity reactions require immediate discontinuation of the Jevtana infusion and appropriate therapy. Jevtana is contraindicated in patients with a history of severe hypersensitivity reactions to cabazitaxel or to other drugs formulated with polysorbate 80 [see Contraindications (4)].

Gastrointestinal Adverse Reactions

Nausea, vomiting and severe diarrhea, at times, may occur. Deaths related to diarrhea and electrolyte imbalance occurred in the randomized clinical trials. Intensive measures may be required for severe diarrhea and electrolyte imbalance. Antiemetic prophylaxis is recommended. Treat patients with rehydration, antidiarrheal or antiemetic medications as needed. Treatment delay or dosage reduction may be necessary if patients experience Grade ≥3 diarrhea [see Dosage and Administration (2.2)].

Gastrointestinal (GI) hemorrhage and perforation, ileus, enterocolitis, neutropenic enterocolitis, including fatal outcome, have been reported in patients treated with Jevtana [see Adverse Reactions (6.2)]. Risk may be increased with neutropenia, age, steroid use, concomitant use of NSAIDs, antiplatelet therapy or anticoagulants, and patients with a prior history of pelvic radiotherapy, adhesions, ulceration and GI bleeding.

Abdominal pain and tenderness, fever, persistent constipation, diarrhea, with or without neutropenia, may be early manifestations of serious gastrointestinal toxicity and should be evaluated and treated promptly. Jevtana treatment delay or discontinuation may be necessary.

​The incidence of gastrointestinal adverse reactions is greater in the patients who have received prior radiation. In PROSELICA, diarrhea was reported in 41% (297/732) of patients who had received prior radiation and in 27% (118/443) of patients without prior radiation. Of the patients who had previously received radiation, more patients on the 25 mg/m2 arm reported diarrhea, compared to patients on the 20 mg/m2 arm.

Renal Failure

In the randomized clinical trial (TROPIC), renal failure of any grade occurred in 4% of the patients being treated with Jevtana, including four cases with fatal outcome. Most cases occurred in association with sepsis, dehydration, or obstructive uropathy [see Adverse Reactions (6.1)]. Some deaths due to renal failure did not have a clear etiology. Appropriate measures should be taken to identify causes of renal failure and treat aggressively.

Urinary Disorders Including Cystitis

​Cystitis, radiation cystitis, and hematuria, including that requiring hospitalization, has been reported with Jevtana in patients who previously received pelvic radiation [see Adverse Reactions (6.2)]. In PROSELICA, cystitis and radiation cystitis were reported in 1.2% and 1.5% of patients who received prior radiation, respectively. Hematuria was reported in 19.4% of patients who received prior radiation and in 14.4% of patients who did not receive prior radiation. Cystitis from radiation recall may occur late in treatment with Jevtana. Monitor patients who previously received pelvic radiation for signs and symptoms of cystitis while on Jevtana. Interrupt or discontinue Jevtana in patients experiencing severe hemorrhagic cystitis. Medical and/or surgical supportive treatment may be required to treat severe hemorrhagic cystitis.

Respiratory Disorders

Interstitial pneumonia/pneumonitis, interstitial lung disease and acute respiratory distress syndrome have been reported and may be associated with fatal outcome [see Adverse Reactions (6.2)]. Patients with underlying lung disease may be at higher risk for these events. Acute respiratory distress syndrome may occur in the setting of infection.

Use in Patients with Hepatic Impairment

Cabazitaxel is extensively metabolized in the liver.

Jevtana is contraindicated in patients with severe hepatic impairment (total bilirubin >3 × ULN) [see Contraindications (4)]. Dose should be reduced for patients with mild (total bilirubin >1 to ≤1.5 × ULN or AST >1.5 × ULN) and moderate (total bilirubin >1.5 to ≤3.0 × ULN and any AST) hepatic impairment, based on tolerability data in these patients [see Dosage and Administration (2.3) and Use in Specific Populations (8.7)]. Administration of Jevtana to patients with mild and moderate hepatic impairment should be undertaken with caution and close monitoring of safety.

Adverse Reactions

The following serious adverse reactions are discussed in greater detail in another section of the label:

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed cannot be directly compared to rates in other trials and may not reflect the rates observed in clinical practice.

TROPIC Trial (Jevtana + prednisone compared to mitoxantrone)

The safety of Jevtana in combination with prednisone was evaluated in 371 patients with metastatic castration-resistant prostate cancer treated in the randomized TROPIC trial, compared to mitoxantrone plus prednisone.

Deaths due to causes other than disease progression within 30 days of last study drug dose were reported in 18 (5%) Jevtana-treated patients and 3 (<1%) mitoxantrone-treated patients. The most common fatal adverse reactions in Jevtana-treated patients were infections (n=5) and renal failure (n=4). The majority (4 of 5 patients) of fatal infection-related adverse reactions occurred after a single dose of Jevtana. Other fatal adverse reactions in Jevtana-treated patients included ventricular fibrillation, cerebral hemorrhage, and dyspnea.

The most common (≥5%) grade 3–4 adverse reactions in patients who received Jevtana were neutropenia, leukopenia, anemia, febrile neutropenia, diarrhea, fatigue, and asthenia.

Treatment discontinuations due to adverse drug reactions occurred in 18% of patients who received Jevtana and 8% of patients who received mitoxantrone. The most common adverse reactions leading to treatment discontinuation in the Jevtana group were neutropenia and renal failure. Dose reductions were reported in 12% of Jevtana-treated patients and 4% of mitoxantrone-treated patients. Dose delays were reported in 28% of Jevtana-treated patients and 15% of mitoxantrone-treated patients.

Table 2: Incidence of Adverse Reactions* and Hematologic Abnormalities in ≥5% of Patients Receiving Jevtana in Combination with Prednisone or Mitoxantrone in Combination with Prednisone in TROPIC

Treatment discontinuations due to adverse drug reactions occurred in 17% of patients in the 20 mg/m2 group and 20% of patients in the 25 mg/m2 group. The most common adverse reactions leading to treatment discontinuation were fatigue and hematuria. The patients in the 20 mg/m2 group received a median of 6 cycles (median duration of 18 weeks), while patients in the 25 mg/m2 group received a median of 7 cycles (median duration of 21 weeks). In the 25 mg/m2 group, 128 patients (22%) had a dose reduced from 25 to 20 mg/m2, 19 patients (3%) had a dose reduced from 20 to 15 mg/m2 and 1 patient (0.2%) had a dose reduced from 15 to 12 mg/m2. In the 20 mg/m2 group, 58 patients (10%) had a dose reduced from 20 to 15 mg/m2, and 9 patients (2%) had a dose reduced from 15 to 12 mg/m2.

Table 3: Incidence of Adverse Reactions* in ≥5% of Patients Receiving Jevtana 20 mg/m2 or 25 mg/m2 in Combination with Prednisone in PROSELICA

In study TROPIC, adverse reactions of hematuria, including those requiring medical intervention, were more common in Jevtana-treated patients. The incidence of grade ≥2 hematuria was 6% in Jevtana-treated patients and 2% in mitoxantrone-treated patients. Other factors associated with hematuria were well-balanced between arms and do not account for the increased rate of hematuria on the Jevtana arm.

In study PROSELICA, hematuria of all grades was observed in 18% of patients overall.

Hepatic Laboratory Abnormalities

The incidences of grade 3–4 increased AST, increased ALT, and increased bilirubin were each ≤1%.

Postmarketing Experience

The following adverse reactions have been identified from clinical trials and/or postmarketing surveillance. Because they are reported from a population of unknown size, precise estimates of frequency cannot be made.

USE IN SPECIFIC POPULATIONS

Pregnancy

Risk Summary

Jevtana is contraindicated for use in pregnant women because the drug can cause fetal harm and potential loss of pregnancy. Jevtana is not indicated for use in female patients. There are no human data on the use of cabazitaxel injection in pregnant women. In animal reproduction studies, intravenous administration of cabazitaxel in pregnant rats during organogenesis caused embryonic and fetal death at doses lower than the maximum recommended human dose [see Data].

Data

Animal data

In an early embryonic developmental toxicity study in rats, cabazitaxel was administered intravenously for 15 days prior to mating through Day 6 of pregnancy, which resulted in an increase in pre-implantation loss at 0.2 mg/kg/day and an increase in early resorptions at ≥0.1 mg/kg/day (approximately 0.06 and 0.02 times the Cmax in patients at the recommended human dose, respectively).

In an embryo-fetal developmental toxicity study in rats, cabazitaxel caused maternal and embryo-fetal toxicity consisting of increased postimplantation loss, embryolethality, and fetal deaths when administered intravenously at a dose of 0.16 mg/kg/day (approximately 0.06 times the Cmax in patients at the recommended human dose). Decreased mean fetal birthweight associated with delays in skeletal ossification was observed at doses ≥0.08 mg/kg. Cabazitaxel crossed the placenta barrier within 24 hours of a single intravenous administration of 0.08 mg/kg to pregnant rats at gestational day 17. A dose of 0.08 mg/kg in rats resulted in a Cmax approximately 0.02 times that observed in patients at the recommended human dose. Administration of cabazitaxel did not result in fetal abnormalities in rats or rabbits at exposure levels significantly lower than the expected human exposures.

Lactation

Risk Summary

Jevtana is not indicated for use in female patients. There is no information available on the presence of cabazitaxel in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production. Cabazitaxel or cabazitaxel metabolites are excreted in maternal milk of lactating rats [see Data].

Data

Animal data

In a milk excretion study, radioactivity related to cabazitaxel was detected in the stomachs of nursing pups within 2 hours of a single intravenous administration of cabazitaxel to lactating rats at a dose of 0.08 mg/kg (approximately 0.02 times the Cmax in patients at the recommended human dose). This was detectable 24 hours post dose. Approximately 1.5% of the dose delivered to the mother was calculated to be delivered in the maternal milk.

Females and Males of Reproductive Potential

Contraception

Males

Based on findings in animal reproduction studies, advise male patients with female partners of reproductive potential to use effective contraception during treatment and for 3 months after the final dose of Jevtana [see Use in Specific Populations (8.1)].

Pediatric Use

The safety and effectiveness of Jevtana in pediatric patients have not been established.

Jevtana was evaluated in 39 pediatric patients (ages 3 to 18 years) receiving prophylactic G-CSF. The maximum tolerated dose (MTD) was 30 mg/m2 intravenously over 1 hour on Day 1 of a 21 day cycle in pediatric patients with solid tumors based on the dose-limiting toxicity (DLT) of febrile neutropenia. No objective responses were observed in 11 patients with refractory high grade glioma (HGG) or diffuse intrinsic pontine glioma (DIPG). One patient had a partial response among the 9 patients with ependymoma.

Infusion related/hypersensitivity reactions were seen in 10 patients (26%). Three patients experienced serious adverse events of anaphylactic reaction. The incidence of infusion related/hypersensitivity reactions decreased with steroid pre-medication. The most frequent treatment-emergent adverse events were similar to those reported in adults.

Based on the population pharmacokinetics analysis conducted with data from 31 pediatric patients with cancer (ages 3 to 18 years), the clearances by body surface area were comparable to those in adults.

Geriatric Use

In the TROPIC study, of the 371 patients with prostate cancer treated with Jevtana every three weeks plus prednisone, 240 patients (64.7%) were 65 years of age and over, while 70 patients (18.9%) were 75 years of age and over. No overall differences in effectiveness were observed between patients ≥65 years of age and younger patients. Elderly patients (≥65 years of age) may be more likely to experience certain adverse reactions. The incidence of death due to causes other than disease progression within 30 days of the last cabazitaxel dose were higher in patients who were 65 years of age or greater compared to younger patients [see Warnings and Precautions (5.2)]. The incidence of grade 3–4 neutropenia and febrile neutropenia were higher in patients who were 65 years of age or greater compared to younger patients. The following grade 1–4 adverse reactions were reported at rates ≥5% higher in patients 65 years of age or older compared to younger patients: fatigue (40% vs 30%), neutropenia (97% vs 89%), asthenia (24% vs 15%), pyrexia (15% vs 8%), dizziness (10% vs 5%), urinary tract infection (10% vs 3%), and dehydration (7% vs 2%), respectively.

Hepatic Impairment

Cabazitaxel is extensively metabolized in the liver. Patients with mild hepatic impairment (total bilirubin >1 to ≤1.5 × ULN or AST >1.5 × ULN) should have Jevtana dose of 20 mg/m2. Administration of cabazitaxel to patients with mild hepatic impairment should be undertaken with caution and close monitoring of safety [see Clinical Pharmacology (12.3)]. The maximum tolerated dose in patients with moderate hepatic impairment (total bilirubin >1.5 to ≤3.0 × ULN and AST = any) was 15 mg/m2, however, the efficacy at this dose level was unknown. Jevtana is contraindicated in patients with severe hepatic impairment (total bilirubin >3 × ULN) [see Contraindications (4)].

Overdosage

There is no known antidote for Jevtana overdose. Overdose has resulted from improper preparation [see Dosage and Administration (2.5)]. Read the entire section Dosage and Administration (2) carefully before mixing or diluting. Complications of overdose include exacerbation of adverse reactions such as bone marrow suppression and gastrointestinal disorders. Overdose has led to fatal outcome.

In case of overdose, the patient should be kept in a specialized unit where vital signs, chemistry and particular functions can be closely monitored. Patients should receive therapeutic G-CSF as soon as possible after discovery of overdose. Other appropriate symptomatic measures should be taken, as needed.

Jevtana Description

Jevtana (cabazitaxel) injection is an antineoplastic agent belonging to the taxane class that is for intravenous use. It is prepared by semi-synthesis with a precursor extracted from yew needles.

The chemical name of cabazitaxel is (2α,5β,7β,10β,13α)-4-acetoxy-13-({(2R,3S)-3-[(tertbutoxycarbonyl) amino]-2-hydroxy-3-phenylpropanoyl}oxy)-1-hydroxy-7,10-dimethoxy-9-oxo-5,20-epoxytax-11-en-2-yl benzoate–propan-2-one (1:1).

Cabazitaxel has the following structural formula:

Cabazitaxel is a white to almost-white powder with a molecular formula of C45H57NO14C3H6O and a molecular weight of 894.01 (for the acetone solvate) / 835.93 (for the solvent free). It is lipophilic, practically insoluble in water and soluble in alcohol.

DILUENT for Jevtana is a clear, colorless, sterile, and non-pyrogenic solution containing 13% (w/w) ethanol in water for injection, approximately 5.7 mL.

Jevtana requires two dilutions prior to intravenous infusion. Jevtana injection should be diluted only with the supplied DILUENT for Jevtana, followed by dilution in either 0.9% sodium chloride solution or 5% dextrose solution.

Jevtana - Clinical Pharmacology

Mechanism of Action

Cabazitaxel is a microtubule inhibitor. Cabazitaxel binds to tubulin and promotes its assembly into microtubules while simultaneously inhibiting disassembly. This leads to the stabilization of microtubules, which results in the inhibition of mitotic and interphase cellular functions.

Pharmacodynamics

Cardiac Electrophysiology

The effect of cabazitaxel following a single dose of 25 mg/m2 administered by intravenous infusion on QTc interval was evaluated in 94 patients with solid tumors. No large changes in the mean QT interval (i.e., >20 ms) from baseline based on Fridericia correction method were detected. However, a small increase in the mean QTc interval (i.e., <10 ms) cannot be excluded due to study design limitations.

Pharmacokinetics

A population pharmacokinetic analysis was conducted in 170 patients with solid tumors at doses ranging from 10 to 30 mg/m2 weekly or every three weeks.

Absorption

Based on the population pharmacokinetic analysis, after an intravenous dose of cabazitaxel 25 mg/m2 every three weeks, the mean Cmax in patients with metastatic prostate cancer was 226 ng/mL (CV 107%) and was reached at the end of the one-hour infusion (Tmax). The mean AUC in patients with metastatic prostate cancer was 991 ng∙h/mL (CV 34%).

No major deviation from the dose proportionality was observed from 10 to 30 mg/m2 in patients with advanced solid tumors.

Distribution

The volume of distribution (Vss) was 4,864 L (2,643 L/m2 for a patient with a median BSA of 1.84 m2) at steady state.

In vitro, the binding of cabazitaxel to human serum proteins was 89% to 92% and was not saturable up to 50,000 ng/mL, which covers the maximum concentration observed in clinical trials. Cabazitaxel is mainly bound to human serum albumin (82%) and lipoproteins (88% for HDL, 70% for LDL, and 56% for VLDL). The in vitro blood-to-plasma concentration ratio in human blood ranged from 0.90 to 0.99, indicating that cabazitaxel was equally distributed between blood and plasma.

Metabolism

Cabazitaxel is extensively metabolized in the liver (>95%), mainly by the CYP3A4/5 isoenzyme (80% to 90%), and to a lesser extent by CYP2C8. Cabazitaxel is the main circulating moiety in human plasma. Seven metabolites were detected in plasma (including the 3 active metabolites issued from O-demethylation), with the main one accounting for 5% of cabazitaxel exposure. Around 20 metabolites of cabazitaxel are excreted into human urine and feces.

Elimination

After a one-hour intravenous infusion [14C]-cabazitaxel 25 mg/m2, approximately 80% of the administered dose was eliminated within 2 weeks. Cabazitaxel is mainly excreted in the feces as numerous metabolites (76% of the dose); while renal excretion of cabazitaxel and metabolites account for 3.7% of the dose (2.3% as unchanged drug in urine).

Based on the population pharmacokinetic analysis, cabazitaxel has a plasma clearance of 48.5 L/h (CV 39%; 26.4 L/h/m2 for a patient with a median BSA of 1.84 m2) in patients with metastatic prostate cancer. Following a one-hour intravenous infusion, plasma concentrations of cabazitaxel can be described by a three-compartment pharmacokinetic model with α-, β-, and γ- half-lives of 4 minutes, 2 hours, and 95 hours, respectively.

Renal Impairment

Cabazitaxel is minimally excreted via the kidney. A population pharmacokinetic analysis carried out in 170 patients including 14 patients with moderate renal impairment (30 mL/min ≤CLCR <50 mL/min) and 59 patients with mild renal impairment (50 mL/min ≤CLCR <80 mL/min) showed that mild to moderate renal impairment did not have meaningful effects on the pharmacokinetics of cabazitaxel. This was confirmed by a dedicated comparative pharmacokinetic study in patients with solid tumors with normal renal function (n=8, CLCR >80 mL/min/1.73 m2), or moderate (n=8, 30 mL/min/1.73 m2 ≤CLCR <50 mL/min/1.73 m2) and severe (n=9, CLCR <30 mL/min/1.73 m2) renal impairment, who received several cycles of cabazitaxel in single IV infusion up to 25 mg/m2. Limited pharmacokinetic data were available in patients with end-stage renal disease (n=2, CLCR <15 mL/min/1.73 m2).

In 3 patients with severe hepatic impairment (total bilirubin >3 × ULN), a 39% decrease in clearance was observed when compared to patients with mild hepatic impairment (ratio=0.61, 90% CI: 0.36–1.05), indicating some effect of severe hepatic impairment on cabazitaxel pharmacokinetics. The MTD of cabazitaxel in patients with severe hepatic impairment was not established. Based on safety and tolerability data, cabazitaxel dose should be maintained at 20 mg/m2 in patients with mild hepatic impairment and reduced to 15 mg/m2 in patients with moderate hepatic impairment [see Warnings and Precautions (5.8) and Use in Specific Populations (8.7)]. Cabazitaxel is contraindicated in patients with severe hepatic impairment [see Contraindications (4) and Use in Specific Populations (8.7)].

Drug Interactions

A drug interaction study of Jevtana in 23 patients with advanced cancers has shown that repeated administration of ketoconazole (400 mg orally once daily), a strong CYP3A inhibitor, increased the exposure to cabazitaxel (5 mg/m2 intravenous) by 25%.

A drug interaction study of Jevtana in 13 patients with advanced cancers has shown that repeated administration of aprepitant (125 or 80 mg once daily), a moderate CYP3A inhibitor, did not modify the exposure to cabazitaxel (15 mg/m2 intravenous).

A drug interaction study of Jevtana in 21 patients with advanced cancers has shown that repeated administration of rifampin (600 mg once daily), a strong CYP3A inducer, decreased the exposure to cabazitaxel (15 mg/m2 intravenous) by 17%.

A drug interaction study of Jevtana in 11 patients with advanced cancers has shown that cabazitaxel (25 mg/m2 administered as a single 1-hour infusion) did not modify the exposure to midazolam, a probe substrate of CYP3A.

Prednisone or prednisolone administered at 10 mg daily did not affect the pharmacokinetics of cabazitaxel.

Based on in vitro studies, the potential for cabazitaxel to inhibit drugs that are substrates of other CYP isoenzymes (1A2,-2B6,-2C9, -2C8, -2C19, -2E1, -2D6, and CYP3A4/5) is low. In addition, cabazitaxel did not induce CYP isozymes (-1A, -2C9 and -3A) in vitro.

In vitro, cabazitaxel is a substrate of P-gp, but not a substrate of MRP1, MRP2, BCRP, OCT1, OATP1B1 or OATP1B3.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

Long-term animal studies have not been performed to evaluate the carcinogenic potential of cabazitaxel.

Cabazitaxel was positive for clastogenesis in the in vivo micronucleus test, inducing an increase of micronuclei in rats at doses ≥0.5 mg/kg. Cabazitaxel increased numerical aberrations with or without metabolic activation in an in vitro test in human lymphocytes though no induction of structural aberrations was observed. Cabazitaxel did not induce mutations in the bacterial reverse mutation (Ames) test. The positive in vivo genotoxicity findings are consistent with the pharmacological activity of the compound (inhibition of tubulin depolymerization).

In a fertility study performed in female rats at cabazitaxel doses of 0.05, 0.1, or 0.2 mg/kg/day there was no effect of administration of the drug on mating behavior or the ability to become pregnant. In repeat-dose toxicology studies in rats with intravenous cabazitaxel administration once every three weeks for up to 6 months, atrophy of the uterus was observed at the 5 mg/kg dose level (approximately the AUC in patients with cancer at the recommended human dose) along with necrosis of the corpora lutea at doses ≥1 mg/kg (approximately 0.2 times the AUC at the clinically recommended human dose).

In a fertility study in male rats, cabazitaxel did not affect mating performances or fertility at doses of 0.05, 0.1, or 0.2 mg/kg/day. In repeat-dose toxicology studies with intravenous cabazitaxel administration once every three weeks for up to 9 months, degeneration of seminal vesicle and seminiferous tubule atrophy in the testis were observed in rats at a dose of 1 mg/kg (approximately 0.2 times the AUC in patients at the recommended human dose), and minimal testicular degeneration (minimal epithelial single cell necrosis in epididymis) was observed in dogs treated at a dose of 0.5 mg/kg (approximately 0.1 times the AUC in patients at the recommended human dose).

Clinical Studies

TROPIC Trial (Jevtana + prednisone compared to mitoxantrone)

The efficacy and safety of Jevtana in combination with prednisone were evaluated in a randomized, open-label, international, multi-center study in patients with metastatic castration-resistant prostate cancer previously treated with a docetaxel-containing treatment regimen (TROPIC, NCT00417079).

A total of 755 patients were randomized to receive either Jevtana 25 mg/m2 intravenously every 3 weeks for a maximum of 10 cycles with prednisone 10 mg orally daily (n=378), or to receive mitoxantrone 12 mg/m2 intravenously every 3 weeks for 10 cycles with prednisone 10 mg orally daily (n=377) for a maximum of 10 cycles.

This study included patients over 18 years of age with hormone-refractory metastatic prostate cancer either measurable by RECIST criteria or non-measurable disease with rising PSA levels or appearance of new lesions, and ECOG (Eastern Cooperative Oncology Group) performance status 0–2. Patients had to have neutrophils >1,500 cells/mm3, platelets >100,000 cells/mm3, hemoglobin >10 g/dL, creatinine <1.5 × upper limit of normal (ULN), total bilirubin <1 × ULN, AST <1.5 × ULN, and ALT <1.5 × ULN. Patients with a history of congestive heart failure, or myocardial infarction within the last 6 months, or patients with uncontrolled cardiac arrhythmias, angina pectoris, and/or hypertension were not included in the study.

Demographics, including age, race, and ECOG performance status (0–2) were balanced between the treatment arms. The median age was 68 years (range 46–92) and the racial distribution for all groups was 83.9% Caucasian, 6.9% Asian, 5.3% Black, and 4% Others in the Jevtana group.

Efficacy results for the Jevtana arm versus the control arm are summarized in Table 5 and Figure 1.

Table 5: Efficacy of Jevtana in TROPIC in the Treatment of Patients with Metastatic Castration-Resistant Prostate Cancer (intent-to-treat analysis)

Demographics, including age, race, and ECOG performance status (0–2) were balanced between the treatment arms. The median age was 68 years (range 45–89) and the racial distribution for all groups was 87% Caucasian, 6.9% Asian, 2.3% Black, and 3.8% Others in the Jevtana 20 mg/m2 group. The median age was 69 years (range 45–88) and the racial distribution for all groups was 88.7% Caucasian, 6.6% Asian, 1.8% Black, and 2.8% Others in the Jevtana 25 mg/m2 group.

The study demonstrated noninferiority in overall survival (OS) of Jevtana 20 mg/m2 in comparison with Jevtana 25 mg/m2 in an intent-to-treat population (see Table 6 and Figure 2). Based on the per-protocol population, the estimated median OS was 15.1 months on Jevtana 20 mg/m2 and 15.9 months on Jevtana 25 mg/m2, the observed hazard ratio (HR) of OS was 1.042 (97.78% CI: 0.886, 1.224). Among the subgroup analyses intended for assessing the heterogeneity, no notable difference in OS was observed on the Jevtana 25 mg/m2 arm compared to the Jevtana 20 mg/m2 arm in subgroups based on the stratification factors of ECOG performance status score, measurability of disease, or region.

Patient Counseling Information

Educate patients about the risk of potential hypersensitivity associated with Jevtana. Confirm patients do not have a history of severe hypersensitivity reactions to cabazitaxel or to other drugs formulated with polysorbate 80. Instruct patients to immediately report signs of a hypersensitivity reaction [see Contraindications (4) and Warnings and Precautions (5.3)].

Bone Marrow Suppression

Inform patients that Jevtana decreases blood count such as white blood cells, platelets and red blood cells. Thus, it is important that periodic assessment of their blood count be performed to detect the development of neutropenia, thrombocytopenia, anemia, and/or pancytopenia [see Contraindications (4) and Warnings and Precautions (5.1)]. Instruct patients to monitor their temperature frequently and immediately report any occurrence of fever to their healthcare provider.

Explain that it is important to take the oral prednisone as prescribed. Instruct patients to report if they were not compliant with oral corticosteroid regimen [see Dosage and Administration (2.1)].

Infections, Dehydration, Renal Failure

Explain to patients that severe and fatal infections, dehydration, and renal failure have been associated with cabazitaxel exposure. Patients should immediately report fever, significant vomiting or diarrhea, decreased urinary output, and hematuria to their healthcare provider [see Warnings and Precautions (5.1, 5.4, 5.5)].

Respiratory Disorders

Explain to patients that severe and fatal interstitial pneumonia/pneumonitis, interstitial lung disease and acute respiratory distress syndrome have occurred with Jevtana. Instruct patients to immediately report new or worsening pulmonary symptoms to their healthcare provider [see Warnings and Precautions (5.7)].

Drug Interactions

Inform patients about the risk of drug interactions and the importance of providing a list of prescription and non-prescription drugs to their healthcare provider [see Drug Interactions (7.1)].

Embryo-Fetal Toxicity

Advise male patients with female partners of reproductive potential to use effective contraception during treatment and for 3 months after the last dose of cabazitaxel injection [see Use in Specific Populations (8.3)].

What is Jevtana?
Jevtana is a prescription anti-cancer medicine used with the steroid medicine prednisone. Jevtana is used to treat men with castration-resistant prostate cancer (prostate cancer that is resistant to medical or surgical treatments that lower testosterone) that has worsened (progressed) after treatment with other medicines that included docetaxel.
Jevtana is not for use in females.
It is not known if Jevtana is safe and effective in children.

Who should not receive Jevtana?
Do not receive Jevtana if:

your white blood cell (neutrophil count) is too low

you have had a severe allergic reaction to cabazitaxel or other medicines that contain polysorbate 80. Ask your healthcare provider if you are not sure.

you have severe liver problems

you are pregnant. Jevtana can harm your unborn baby or possibly cause loss of pregnancy.

Before receiving Jevtana, tell your healthcare provider about all your medical conditions, including if you:

had allergic reactions in the past

have kidney or liver problems

have lung problems

are over the age of 65

are a male with a female partner who is able to become pregnant. Males should use effective birth control (contraception) during treatment with Jevtana and for 3 months after your final dose of Jevtana.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Jevtana can interact with many other medicines. Do not take any new medicines without asking your healthcare provider first. Your healthcare provider will tell you if it is safe to take the new medicine with Jevtana.

How will I receive Jevtana?

Jevtana will be given to you by an intravenous (IV) infusion into your vein.

Your treatment will take about 1 hour.

Jevtana is usually given every 3 weeks. Your healthcare provider will decide how often you will receive Jevtana.

Your healthcare provider will also prescribe another medicine called prednisone for you to take by mouth every day during treatment with Jevtana. Your healthcare provider will tell you how and when to take your prednisone.

It is important that you take prednisone exactly as prescribed by your healthcare provider. If you forget to take your prednisone, or do not take it on schedule, make sure to tell your healthcare provider or nurse. Before each infusion of Jevtana, you may receive other medicines to prevent or treat side effects.

What are the possible side effects of Jevtana?
